Category:Pages with broken reference names

This is a maintenance category. It is used for maintenance of the Wikipedia project and is not part of the encyclopedia. It contains pages that are not articles, or it groups articles by status rather than content. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference 'Show hidden categories' is set. This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. Pages are added to tracking categories through templates.

This category has a backlog that requires the attention of willing editors. This notice will hide itself when this category has fewer than 50 items. (recount)

Pages are placed in this category when any of the following cite errors are generated on the page:

• The named reference $1 was invoked but never defined (see the help page).

Where $1 is the <ref> tag name.

Please do not delete the ref nor comment it out. This error usually occurs because someone deleted another ref with that same name that had text in it. To fix these errors, look in the page history to find the deleted ref and copy its text into the remaining ref with the error message. To find first entry of ref use WikiBlame. AnomieBOT does some fixes and often leaves helpful suggestions on an article's Talk page.
